A Statistical Mechanical Model of Cholesterol/Phospholipid Mixtures: Linking Condensed Complexes, Superlattices, and the Phase Diagram
2011
Journal of the American Chemical Society
Despite extensive studies for nearly three decades, lateral distribution of molecules in cholesterol/ phospholipid bilayers remains elusive. Here we present a statistical mechanical model of cholesterol/phospholipid mixtures that is able to rationalize almost every critical mole fraction (X cr ) value previously reported for sterol superlattice formation as well as the observed biphasic changes in membrane properties at X cr . This model is able to explain how cholesterol superlattices and
